Principle

A measurement cuvette set in the beam path of a Michelson interferometer can be evacuated or filled with CO2. The refraction indexes of air or CO2 are determined through the assessed modification of the interference pattern.

Benefits

  • see that even two transparent gases can have different optical properties
  • a Michelson interferometer is used to measure subtle differences in the refractive indices
  • thoughtful engineered components allow effective experimenting

Tasks

1.  Determine the refraction index of air,

2. Determine the refraction index of CO2.
